铁路信号供电的可靠性探讨

Discuss of Reliability on the Power Supply for Railway Signal

通过对目前铁路信号供电中存在问题的分析,论述了电源内的高次谐波、双电源回路同时停电、单电源回路故障停电对信号系统的影响,介绍了采用交直交电源装置使用效果,为电化区段、非电化区段,单、双回路供电提供可靠电源的技术方案。

By analyzing the problem of the railway signal power supply at present, this paper discussed the infection about power harmonic and double - loop feeding cut at the sime time and single feeding failure cut, introduced performance of AC - DC - AC supply dvice and provided the scheme about reliable power supply for electrization railway and nonelectrization railway.
